Product Review

I ADORE this pen. Out of the few I've bought and tried from this site so far,
this has been the clear favorite. As has already been noted, it isn't
waterproof, which was distressing the first time I tried to watercolor over a
drawing done with this pen. Oh well, lesson learned. Seems to work fine with my
copics. Lovely lines. The best non-bristle brush pen I have ever used.
